New Advances in Chemical Research, April 2021.The transformation of simple hydrocarbons into more complex has revolutionised modern synthetic chemistry. This type of reactivity has quickly become one of the cornerstones of modern catalysis .1588-83-6, Name is 4-Amino-3-nitrobenzoic acid, SMILES is C1=C([N+]([O-])=O)C(=CC=C1C(=O)O)N, belongs to naphthyridine compound. In a document, author is Tverdokhlebov, AV, introduce the new discover, Quality Control of 4-Amino-3-nitrobenzoic acid.
2-Amino-4-cyanomethyl-6-dialkylamino-3,5-pyridinedicarbonitriles were found to react with substituted oxiranes yielding 5,6-diamino-8-dialkylamino-1,2-dihydrofuro [2,3-c]-2,7-naphthyridine-9-carbonitriles. The oxirane ring was shown to be opened selectively from the unsubstituted side and further cyclization occurred with participation of 3-CN, but not 5-CN of the starting pyridines. The furonaphthyridines obtained were converted into 2-dialkylamino-5-methyl-9,10-dihydro-4H-furo[2,3-c]pyrimido[4,5,6-ij]-2,7-naphthyridine-l-carbonitriles and 2-dialkylamino-5,6,9,10-tetrahydro-4H-spiroffuro[2,3-c]pyrimido[4,5,6-ij]-2,7-naphthyridine-5,1′-cyclohexane}1-carbonitriles by treatment with acetic anhydride and cyclohexanone, respectively. The structure of prepared compounds was confirmed unambiguously by X-ray crystallographic study. (c) 2005 Elsevier Ltd. All rights reserved.
The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.Welcome to check out more blogs about 1588-83-6, in my other articles. Quality Control of 4-Amino-3-nitrobenzoic acid.
